代码说明:

本代码是实现lt码的编解码过程,码长K=1000,N=1000:50:2000,间隔为50,c=0.1,delta=0.7,显示结果为随着N值的增大,误码率降低,当N=1200时,译码失败率为10%,当N=1300时,译码失败率为0,所以随着N值的增大,译码失败率显著降低,在二元删除信道中表现十分良好,但是在高斯白噪声的信道环境下,误码率还是有所降低。

  • tick2text
    This function creates text objects that mimic x and y tick labels, while the original tick labels are removed. The text object format allows more modification (such as color, rotation, etc) than the original tick labels, and also allows TeX strings to be utilized in tick labels (see xformat and yformat inputs for more details).

  • matlab 实现 车牌识别程序
    说明:  车牌识别系统(Vehicle License Plate Recognition,VLPR) 是计算机视频图像识别技术在车辆牌照识别中的一种应用。车牌识别在高速公路车辆管理中得到广泛应用,电子收费(ETC)系统中,也是结合DSRC技术识别车辆身份的主要手段。(Vehicle License Plate Recognition (VLPR) is an application of computer video image recognition technology in vehicle license plate recognition. License plate recognition is widely used in highway vehicle management. In the electronic toll collection (ETC) system, it is also the main means to identify the identity of vehicles in combination with DSRC technology.)
